What is the difference between GHRP-6 and Semax?
GHRP-6 is one of the earliest synthetic growth hormone secretagogue hexapeptides, used as a ghrelin receptor (GHS-R1a) agonist in endocrine research (peptide, MW about 873 g/mol).
Which is heavier, GHRP-6 or Semax?
GHRP-6 has a molecular weight of about 873 g/mol and Semax about 813.9 g/mol (PubChem), so GHRP-6 is heavier by 59.1 g/mol, a ratio of 1.07. This means 1 mg of GHRP-6 contains 1,145.5 nmol versus 1,228.7 nmol for Semax.
How many mg of Semax are equimolar to 1 mg of GHRP-6?
1 mg of GHRP-6 (MW 873) is 1,145.5 nmol. The same number of moles of Semax (MW 813.9) weighs 0.9323 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
Compare the molecular formulas of GHRP-6 and Semax
PubChem lists GHRP-6 as C46H56N12O6 (873 g/mol) and Semax as C37H51N9O10S (813.9 g/mol). GHRP-6 is a peptide; Semax is a peptide. These formulas refer to the parent compounds without salt counter-ions.
A 5 mg vial of GHRP-6 equals how many mg of Semax in moles?
5 mg of GHRP-6 (MW 873) is 5.727 µmol. The same amount of Semax (MW 813.9) would weigh 4.662 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of GHRP-6 equals how many mg of Semax in moles?
10 mg of GHRP-6 (MW 873) is 11.455 µmol. The same amount of Semax (MW 813.9) would weigh 9.323 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 5 mg vial of Semax equals how many mg of GHRP-6 in moles?
5 mg of Semax (MW 813.9) is 6.143 µmol. The same amount of GHRP-6 (MW 873) would weigh 5.363 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Semax equals how many mg of GHRP-6 in moles?
10 mg of Semax (MW 813.9) is 12.287 µmol. The same amount of GHRP-6 (MW 873) would weigh 10.726 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 30 mg vial of Semax equals how many mg of GHRP-6 in moles?
30 mg of Semax (MW 813.9) is 36.86 µmol. The same amount of GHRP-6 (MW 873) would weigh 32.178 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
